Causes An AC PCB To Become Damaged
An AC electrical circuit board is a large piece of metal that houses the components and wiring, which enables the AC service in Noida unit to work. An air conditioner’s PCB (printed circuit board) is the heart of your AC unit. It controls the fan speed, compressor and refrigerant charge level, pressure relief valve and other important functions. The PCB has a lot of wires running through it, so it can easily become damaged over time.
The most common cause of an air conditioner’s PCB damage is the wires becoming loose or disconnected from the circuit board. Wire insulation breaks down over time due to heat and moisture, causing the wire to lose its connection point on the board.
Other causes of damage include corrosion and water damage due to improper maintenance or installation, electrical surges, dust, and dirt.
Electrical Surges
Electrical surges can occur when an appliance is left on for long periods or when someone plugs in or unplugs an appliance while it is still running. When this happens, the electricity travels through the wires on the AC PCB and damages them.
Dust and Dirt
Dust and dirt may cause damage by clogging up the microscopic pores on these boards or by shorting out one or more of these pores with other substances, such as grease or debris particles.
Moisture
Moisture causes damage to an air conditioner’s printed circuit board (PCB). The PCB is a vital component in any air conditioner as it controls the functions and operations of the unit. When moisture enters the PCB, it can cause corrosion and other damage, leading to costly repairs or complete system failure. Moisture can also damage an AC’s PCB by swelling it and causing it to expand beyond its normal size.
Loose or Disconnected Wire
Loose or disconnected wires are among the most common causes of damage to an
AC PCB board. When a wire becomes loose or disconnected, it can cause a short circuit, damaging the PCB board and leading to costly repairs. To prevent this, the wires regularly and ensure they are properly connected and secured. Regular maintenance is essential to keep your air conditioner running smoothly and efficiently.
Corrosion And Water Damage
The AC PCB board of an air conditioner is one of the most important parts and can be easily damaged due to corrosion and water damage. Corrosion occurs when moisture accumulates on the PCB board, leading to oxidation and eventual destruction of the components. On the other hand, water damage can occur when condensation from air conditioners leaks onto the PCB board, causing it to short circuit or corrode. Both corrosion and water damage can cause irreparable harm to an AC’s PCB board if not dealt with quickly.

Reasons For AC PCB Problems
The air conditioning system is a critical component of the building’s infrastructure. The equipment is responsible for maintaining a comfortable environment in the building, which is why it must be kept in good condition.
The AC unit consists of several electrical components that perform various functions. These include
- The blower motor is responsible for taking air from the outside and distributing it throughout the building.
- The compressor works to increase pressure in the refrigerant.
- The condenser cools down the refrigerant so that it can be reused.
- Several factors can cause these components to fail, causing them to stop working properly or even destroying them completely.
However, electrical surges and dust in the system can cause the AC’s PCB to become damaged. Electrical surges are caused by power surges that enter a home or building. These can be caused by lightning strikes, power outages, power lines touching objects like trees or fences, electrical wires hitting power lines and other causes.
All these types of damage can cause deterioration to a PCB board aircon. Electrical dust can cause damage because it collects on the AC’s PCB, shorting out its components and causing them to overheat and burn out. Moisture is also a major cause of AC PCB failures. Moisture entering any part of an air conditioning system harms it because it can corrode the metal parts inside an air conditioner unit.
This type of damage has a lot of implications for your home’s comfort level and safety issues. Loose and disconnected wires are also very common causes of AC PCB damage because they allow electricity to flow through them without any protection, which can cause fires or explosions if there aren’t proper protections. Additionally, corrosion is another major reason a PCB board aircon may fail due to moisture entering it. Moisture entering any part of an air conditioning unit is harmful.
Here Are Some Other Reasons
Power Failure
If the AC PCB is not receiving an adequate power supply, it may not function properly. Check the power connection and voltage supply to ensure the PCB receives sufficient power.
Faulty Relay
A faulty relay can cause the AC to turn off or on at random intervals. Check the relay for any signs of damage or wear and replace it if necessary.
Sensor Malfunction
The sensor on the AC PCB may malfunction if it gets dirty or damaged, causing the unit to run inefficiently or stop working altogether. Clean the sensor or replace it if it’s damaged to ensure the proper functioning of the AC.
Capacitor Issues
If the capacitor on the PCB is damaged, it can cause the AC to stop working or run erratically. Check the capacitor for any signs of damage or wear and replace it if necessary.
Solutions For PCB Problem In AC
Electrical surges, dust and dirt, moisture, loose and disconnected wire, and corrosion and water damage are the main causes of AC PCB damage. To prevent these problems, you should clean your AC’s PCB regularly. These damages can cause serious deterioration to the circuitry of AC’s PCB. To keep your AC running at full capacity all the time, you should periodically clean out your AC’s PCB with a soft cloth.
You should also ensure that your electrical devices are plugged in correctly, that there is no dust or dirt in the AC’s circuit board, and that all wires are properly connected to their respective devices. Cleaning the PCB will reduce the occurrence of electrical surges, dust and dirt, moisture, loose and disconnected wire, and corrosion and water damage.
Steps to Clean AC PCB
The following are some ways to clean your AC’s PCB:
- Use a soft brush to remove dust from the surface of the PCB.
- Use a vacuum cleaner to suck up any dirt or dust stuck on the surface of the PCB.
- Wipe down the entire surface of your AC’s PCB with a damp cloth to remove any? remaining dirt or dust particles.
Can a PCB Be Repaired?
The short answer is yes. A PCB can be repaired, but it will never look new again. The good news is that the board’s functionality will not be affected, and it will still be able to perform its intended function. It won’t look as beautiful or shiny as it once was.
If you have a damaged air conditioner PCB, you must ensure your product can still be made without problems. PCB repair is an effective solution for these issues but has some limitations.
However, it is not possible to repair all damaged boards. Some damage is irreversible, and some are repairable. Repairs are done by replacing components with new ones. A process called reflow soldering is used to join the components. The reflow process ensures that every connection between components is made as quickly and cleanly as possible. This is known as “fixing” the part and can result in higher production yields and improved product performance.
Ultimately, it is always advised to engage the services of reputable professionals or companies like Keyvendors to repair an AC PCB to get a guaranteed service ans repair for your device.
Conclusion
There are many reasons why AC PCBs may not be working, but most of these issues can be resolved. Determining whether the issue is with the input or output voltage or the circuit itself is important. If you have AC or DC input and require a protective circuit, then AC PCB is your best option. With air conditioner PCB, you have lesser current flow, thereby allowing lower power dissipation and lesser circuit heat generated, making it more efficient protection against failure.
